Little explanation since I just made this up
Soulmate AU
•Every person in Kunimi's family has a Soulmate
•If your soulmate hurts you a heart string will snap
•If too much heart strings snapped you will die since your heart will get disorted
•They need to choose a soulmate
•If they don't find a soulmate they will get sick or die
•Kindaichi is Kunimi's soulmate
•If a string snaps you will get trouble with breathing and it will feel like something got ripped out of your heart
Your opinion on this soulmate AU?
